Hi Misha,
I have looked at your images several times. I think I prefer the last two the most - and entirely for subjective reasons. I like the intensity of the skies in the 2nd and 3rd images the most. The last is my favorite because the forground is also moderately clearer as well.
Over-all, an excellent effort. These are some of the best images you have posted here to date (in my opinion).
Thank you
James
